Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, torque wrench, brake cleaner, and a socket set.
Raise the vehicle using the jack and secure it with jack stands. Remove the wheels to gain access to the braking components.

2. Inspect Brake Pads

Remove the caliper bolts using a socket set.
Carefully lift the caliper off the rotor without disconnecting the brake line.
Inspect the brake pads for wear. If they are worn down to less than 3mm, they need to be replaced.

3. Inspect Brake Rotors

Check the rotor surface for grooves, scoring, or excessive wear.
If the rotors are damaged or below the minimum thickness specification, they should be resurfaced or replaced.

4. Replace Brake Pads (if necessary)

Remove the old brake pads from the caliper bracket.
Apply brake grease to the backing of the new pads (avoid contact with friction material).
Install the new brake pads into the caliper bracket.

5. Reassemble and Torque

Carefully reposition the caliper over the new pads.
Reinstall the caliper bolts and tighten them to the manufacturer’s specified torque (typically around 25-35 ft-lbs).
Reinstall the wheels and lower the vehicle.
